Report from the President

Dear Society of Rheology Members:

I am delighted to announce that John Brady has agreed to serve as the next Editor of the Journal of Rheology. We are very fortunate that John is willing to take on this important role in the Society; in addition to John’s distinguished stature as a researcher and educator, he has extensive editorial experience through his long association with the Journal of Fluid Mechanics. John was the first choice of a Search Committee consisting of Kurt Wissbrun (chair), Gary Leal, and Bill Russel, and was asked to serve as the next Editor by vote of the Executive Committee. John will serve as Editor designate from July 1, 2005 until the next election in October 2005.

John will replace Mort Denn, who will officially be ending his tenure as Journal of Rheology Editor on July 1, as announced in the most recent Rheology Bulletin. We are all indebted to Mort for his exemplary service as Editor over the past ten years. Under Mort’s leadership, the Journal has maintained the highest ISI Impact Factor of any research journal in the entire field of mechanics, manuscript review and processing times have been kept to a minimum due to his diligence and judgment, and the quality of papers published in the Journal has been exceptional. In addition, Mort’s advice and counsel as a member of the Executive Committee have been invaluable. I hope you will all take this opportunity to thank Mort for his tremendous service to the Society.

Susan J. MullerI would also like to thank Kurt Wissbrun, Gary Leal, and Bill Russel for their very careful, thoughtful, and thorough efforts in conducting the search process for the new Editor.

Sincerely,
Susan J. Muller
President, The Society of Rheology

Distinguished Suspension Rheologist is New JOR Editor

John F. BradyJohn F. Brady, Chevron Professor of Chemical Engineering at California Institute of Technology, has agreed to serve as editor of the Journal of Rheology. The current editor, Morton M. Denn, announced in April that he would step down from that position at the end of June, 2005. Brady, currently associate editor of the Journal of Fluid Mechanics, has been appointed by the SOR Executive Committee to serve out the remainder of Denn’s term of office, which expires in October, 2005. Brady will stand for election to the editor’s position in the fall 2005 Society of Rheology officer elections.

Brady received his M.S. and Ph.D. in chemical engineering from Stanford University and spent four years at the Massachusetts Institute of Technology before moving to the California Institute of Technology in Pasadena, CA USA. He was promoted to full professor at Caltech in 1990, served as departmental executive officer from 1993-1999, and in 1999 was appointed Chevron Professor of Chemical Engineering at Caltech. Brady is a member of the U.S. National Academy of Engineering and a Fellow of the American Physical Society, and has received numerous awards for his professional accomplishments. He has published 89 papers, four book chapters, and many conference proceedings.

Brady’s work is in the area of suspension rheology, and he is well known as the originator, with G. Bossis, of the simulation technique known as Stokesian dynamics (J. Chem. Phys. 80, 5141-5154, 1984). The Stokesian dynamics technique provides a method of simulating the dynamics of dense systems with accurate hydrodynamics and with the contributions of interparticle forces factored in. The development of the Stokesian dynamics technique is considered to be one of the key developments in suspension mechanics of the last 25 years. Stokesian dynamics addresses the kinematics of systems that are not approachable in other ways. Suspensions operate at length scales that are at the boundary between classical continuum mechanics length scales and smaller length scales that require consideration of individual particles (usually addressed in statistical mechanics). In the colloidal regime, microstructural elements (particles, discrete phases, individual molecules) interact via colloidal, hydrodynamic, and Brownian forces. Examples of fluids for which these length scales are important include suspensions, colloidal dispersions, liquid crystals, ferro- and electrorheological fluids, polymer solutions, and polymer melts.

Modeling using the Stokesian dynamics technique begins with the Langevin equation (mixed continuum/Brownian expression for forces on particles) with inertia neglected. The further assumption is made that the fluid obeys the Stokes equation; that is, that particles are within the low Reynolds-number regime. This assumption allows the hydrodynamic forces to be written as a linear function of the velocity. Particles are followed as they interact from one time-step to another, and velocities are calculated for a large number of particles. This technique has been employed by research groups around the world and has been extended to deformable particles and to include inertial effects.

The search for a new JOR editor was conducted by a committee consisting of SOR members (and Bingham medalists) Kurt Wissbrun (chair), Gary Leal, and Bill Russel. “John was the first choice of a Search Committee,” said SOR President Susan Muller in a letter to the membership. “We are very fortunate that John is willing to take on this important role in the Society.” “I look forward to continuing the excellent work of my predecessor,” says Brady, “and to increasing JOR’s reach and impact as rheology expands into new areas of complex material behavior.”

Fun with Bubbles

Who has not seen air bubbles rising in an aquarium, discrete, detached bubbles providing needed oxygen for the colorful fishes swimming nearby? Most would ignore the bubbles and watch the fish flitting around the tank, but for someone with his mind on fluid mechanics, it is the bubbles that capture the imagination. What kind of bubbles would be produced if instead of water, some other fluid were used? Maybe an interesting fluid could be found at the local superstore, perhaps regular liquid hand soap would do the trick?

The question seems unremarkable, and on first guess the answer is obvious: probably nothing would happen, except that the bubbles would rise more slowly. While the bubbles do certainly rise more slowly, that's not the half of it, as discovered by Professor Igor Kliakhandler of the Department of Mathematical Sciences at Michigan Technological University USA. Kliakhandler bought the hand soap and a small aquarium pump and bubbled air through the fluid. He discovered that air rising in liquid hand soap does not always produce discrete bubbles; instead, under certain conditions the air bubbles form long, stable, connected chains. These bubble necklaces or sausage-links were just the beginning of a chain of surprises produced by this simple experiment.

In Newtonian liquids such connected sausage-links do not appear. As Kliakhandler found, the presence of long-chain polymers is critical to bubble-chain formation. He believes that the elastic properties of the polymers help the bubbles to stay connected (Phys. Fluids 14, 3375-3379, 2002). Many basic questions about the phenomenon are not yet answered; Kliakhandler continues his studies of these bubble chains with the support of a grant from the U. S. National Science Foundation. Direct application of the phenomenon thus far is in the manufacture of toys or novelty items such as a version of a lava lamp. Kliakhandler has applied for a patent for his discovery (submitted). He continues to study bubble effects in both water-based and organic polymer solutions.

Every year the journal Physics of Fluids features award-winning photographs and videos chosen from among numerous entries in the Gallery of Fluid Motion exhibit. Kliakhandler's photo of a bubble chain in hand soap was included in the Gallery of Fluid Motion 2002, and was published in Physics of Fluids, 15, S14, 2003 (see all winning entries in the Gallery of Fluid Motion at pof.aip.org/pof/gallery/). Photographs and videos included in the Gallery of Fluid Motion illustrate both experimental and numerical investigations of a wide variety of flow phenomena and are judged by a distinguished international panel of referees. Winning entries are selected based upon criteria of scientific merit, originality, and artistry/aesthetic appeal.

Kliakhandler's photo of linked bubbles was his second award-winning photo in the Gallery of Fluid Motion. The first contribution was also the result of a very simple flow system: Kliakhandler created viscous liquid beads on a vertical fiber, using just an aquarium pump and a length of fishing line (JFM, 429, 381-390, 2001). The fishing-line photo was included in the Gallery of Fluid Motion in 2000. These photos and more are available on the web at www.math.mtu.edu/~igor.

Kliakhandler continues to play with rheologically interesting liquids. The fact that his results have come from simple experiments is by design and by necessity, since Kliakhandler does not consider himself much of an experimentalist. “I’m pleased that there are some simple phenomena that are still around to be discovered,” says Kliakhandler.

ICR2004 Report from Seoul

More than 600 rheologists convened in Seoul South Korea 22-27 August 2004 for the XIVth International Congress on Rheology. Hosted by the Korean Society of Rheology, this event was a phenomenal success.

Professor Jae Chun Hyun, Chairman of the ICR2004 Organizing Committee welcomed delegates to the technical program and chaired the opening plenary delivered by David Boger from the University of Melbourne Australia. Over the five days of technical talks, 490 papers were presented. Attendees were well cared for in the luxury hotels of downtown Seoul, and the convention site, the COEX center, was situation on top of an extensive subterranean mall that catered to every need.

The meeting organizers arranged a social program that began with the opening reception on Sunday and included excursions on Wednesday to either the Changdukgung or Kyungbokgung royal palaces. The afternoon excursions were followed by a barbecue dinner, the scope of which overwhelmed participants. The outdoor location at the Water Stage, Olympic Park, was picture-perfect. The weather cooperated and attendees feasted on roast pork, kim chi and other Korean specialties as well as sushi and sashimi. The dinner was followed by a drumming performance in front of Mongchon Lake, constructed for 1988 Seoul Olympic Games. Nearby, local teenagers were enjoying the Olympic venue, racing around on in-line skates or performing intricate balancing maneuvers on skates.

The crowning social event of ICR2004 was the Thursday banquet back at the COEX Intercon Hotel. Delegates heard a report from David James (University of Toronto Canada), Secretary to the International Committee on Rheology, indicating that the state of rheology world-wide was good, although the number of members of national societies of rheology has slightly declined. James was thanked for his many years of service to rheology as secretary to the ICR. Prof. Hyun was elected by the Committee as a new chairman of the ICR, and Manfred Wagner from Technischen Universitat Berlin Germany was elected to serve as the new secretary.

Two Beginners’ Short Courses Offered in Lubbock

In a break with tradition, there will be two short courses offered at the next meeting of The Society of Rheology. “Beginning Rheology,” a two-day short course on rheology basics, will be offered on February 12 and 13, 2005. The instructors for the course will be Professor Faith Morrison from Michigan Technological University and Professor A. Jeffrey Giacomin from the University of Wisconsin Madison.

The second course will be a one-day class on “Rheological Data Analysis and Comparison to Theory,” by Professor Henning Winter of the University of Massachusetts Amherst, and it will run on February 13, 2005. Students may mix and match between the two short courses, attending Day 1 of the Beginning Rheology course and moving on to the Data Analysis course for the second day.

All classes will convene at the Holiday Inn and Towers in Lubbock, Texas; details are on the web at www0.rheology.org/sor/short_course/2005Feb/. The short courses are held in conjunction with the Annual SOR Meeting.

The Beginning Rheology course is meant for those with little or no background in rheology or rheological modeling. The course content is based on the text Understanding Rheology, by Faith Morrison (Oxford, 2001), which may be ordered at a discount at the time of registration for delivery at the short course.

Rheology News

Annual European Rheology Conference to run this Spring in Grenoble

The Annual European Rheology Conference will be held April 21-23, 2005 in Grenoble, France. The 2nd Circular and more details are available on the web at www.rheology-esr.org/AERC/2005/files/2nd_circular.pdf. Early registration for AERC 2005 closes February 28th 2005.

Dueling Elongational Rheometer Fixtures

In July 2004 TA Instruments announced the development of an attachment to their ARES shear-rheometry platform that allows the measurement of elongational viscosity (www.tainst.com/email/hotline/summer2004/). Dubbed the ARES-EVF – for Elongational Viscosity Fixture - this fixture performs extensional measurements up to a Henky strain of 4.9 at elongational rates of up to 10 s-1.

The development of the ARES-EVF follows the 2003 introduction by Xpansion Instruments of the Sentmanat Extensional Rheometer Universal Testing Platform (SER-UTS). That instrument is also designed to measure elongational viscosity on the ARES platform (Rheol. Bull. 73(1) 12 (2004); Rheol. Acta. 43 657 (2004); www.xinst.com). Both instruments translate the rotational motion and torque measurement capability of the ARES into elongation motion by winding up and stretching samples on two counter-rotating drums. Xpansion also makes versions of the SER that work on the Rheometrics (now TA) RDA-2, RDA-3, and RMS-800 as well as versions for the Paar Physical MCR and the Bohlin (Malvern) VOR.

Priced comparably ($14,500 for the ARES-EVF and $13,900 for the SER-UTS) both instruments are currently in production. The SER device (US patent 6 691 569) produces a flow in which the deformation zone is in a fixed plane. This allows the strain to be validated and produces a flow that is easy to visualize and to adapt to optical techniques. The ARES-EVF (patent pending) produces its flow by putting one drum in motion, wrapping itself around its counter-rotating partner.

New PiezoRheometer Developed

The University of Louis Pasteur Strasbourg, France announces the development of a shear and compression piezo-rheometer. The piezo-rheometer uses piezo-electrical ceramics to apply a strain to a small sample (less than 30 mg) and to subsequently measure the stress generated. The device is targeted at the measurement of the dynamics of soft condensed matter systems such as materials near the sol-gel transition, polymers, liquid-crystalline polymers and elastomers, particles dispersed in gels and biological materials. For more information contact Nicolas.Langlet@ulp-industrie.u-strasbg.fr.

JOR Submission Goes Electronic

The Journal of Rheology will transition to exclusive electronic submission and handling of journal articles over the next 6 months. The change to mandatory electronic submission, adopted by the SOR Executive Committee in April 2004, will reduce the paperwork associated with manuscript handling and is projected to reduce costs at the Journal.

To handle this change, the SOR Exec Com authorized the purchase of PeerX-Press (PXP), software recommended by SOR staff at the American Institute of Physics. The next Editor of the JoR, John Brady, will oversee the transition of the Journal to the new system, which will be optional between January and July 2005, and mandatory after July 2005.

Student Corner

Student Poster Competition in Lubbock

The deadline for submitting materials to the SOR Student Poster Competition in Lubbock is midnight (EST) January 17, 2005. The SOR sponsors a student poster competition to encourage student presentations and participation in SOR meetings and to recognize excellence. In order to be considered in the competition, student poster presenters must also submit a PowerPoint-type poster in PDF format to the chair of the poster session.

A panel of judges will select up to 8 finalists based on the entries, with the final selection of the winner to be made at the poster session. An award of $200 will be made to the winner. For more details see www0.rheology.org/sor/annual_meeting/2005Feb/poster_competition.htm.

APS Congressional Science Fellow Awards

The American Physical Society invites applications for Congressional Science Fellow positions. Through this program APS aims to bring together Members of Congress and individuals with scientific knowledge and skills.

Macosko and Zhao Receive the 2004 SOR Publication Award

Christopher Macosko and Rui Zhao have been selected to receive the 2004 Society of Rheology Publication Award for their paper “Slip at polymer-polymer interfaces: Rheological measurements on coextruded multilayers,” J. Rheology, 46, 145-167 (2002). The award, which consists of a certificate and US $1000 shared among the coauthors, will be presented at the Lubbock meeting in February 2005. Macosko will also be receiving the Bingham Medal of The Society of Rheology in Lubbock, marking the first time that an individual has been so doubly honored in one meeting.

The Journal of Rheology Publication Award Committee annually selects an outstanding paper published in the Journal of Rheology during the preceding two years for special recognition at the annual meeting. The 2004 Publication Award Committee consisted of Journal Editor Morton Denn, two at-large members of the ExCom, and two former winners. The Publication Award, first presented in 1994, is currently sponsored by TA Instruments of New Castle, Delaware.
